Text representation is one of the fundamental problems in text mining and Information Retrieval (IR). It aims to numerically represent the unstructured text documents to make them mathematically computable. For a given set of text documents D = {di, i=1, 2,...,n}, where each distands for a document, the problem of text representation is to represent each di of D as a point siin a numerical space S, where the distance/similarity between each pair of points in space S is well defined.
